So i accidentally started a restore bookmarks by a misclick, this caused my firefox to hang so i had to kill the process. now all my bookmarks were gone, i have tried to restore them using both the import and backup firefox has, ive tried to convert a previous json file into sql but that only worked partly, firefox just starts hanging indefinitely whatever recovery method i try. i tried deleting the sqlite and favicon files mentioned in other posts but that didn't help either

If you have sync, and there is a problem anywhere, Shut Down Sync Immediately On All Devices to prevent the problem from spreading. Once the problem is fixed, perform the same repair on all computers/profiles before using sync again.


[v57+] Places Maintenance is built into Firefox.

Type about:support<enter> in the address bar.

You will find Places Database near the bottom. Press the Verify Integrity button.

If any errors are reported, check this link: https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional

The places.sqlite file contains your History and Bookmarks. And it looks like it is corrupted.

Type about:support<enter> in the address bar.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Locate the above file. Then rename or delete it. Restart Firefox. The browser should then create a new place.sqlite and recover your bookmarks from the backup files.

Note: Your history is not backed up and will be lost.

How many bookmarks are in the file and what is the file size  ?

If the file size and the number of bookmarks is very large then it can take considerably more time to restore a JSON backup. You can try this at some spare time and let the restore process running for a long time.

this is what a 100% working file of my bookmarks is called: bookmarks-2021-06-10_28981_H9VgfFDHuEEJHbv91CiYqw==.jsonlz4

the issue is to get firefox to accept the restoration, but it seems to disregard it and use some other source or just hang, i left it restore this overnight and some weird version of it came back, like firefox is using some other source to restore from.

That file contains 28981 bookmarks, so it shouldn't be a big surprise that it takes a long time to process the bookmarks and you will have to wait a lot longer to see whether the restore finishes.
